Clients often ask, "How can we get started?" The answer is never the same. Sometimes it starts with a new idea. Other times it begins with a design concept relayed over the telephone or a napkin sketch created on the fly. And occasionally, clients provide us with an extensive set of engineered drawings.
No matter where you are with your project, your knowledge of magnetic shielding, or your fabrication expertise, we thrive on working through the details and developing high-performance shielding solutions. Whether you have a detailed design or a concept in the making, our ability to provide you with strategies, calculations, design details, estimates, and manufacturing expertise can help you transform your ideas into reality.
So, regardless of where you are in your project, give us a call. We are always available as a technical resource and collaborator.
Magnetic shield design is a collaborative effort that relies on the knowledge of your system and your requirements with our expertise in magnetic modeling to precisely design and manufacture the optimal shield for your specific application. The following sections outline additional factors that must be considered when designing a shield that will be engineered, fabricated, and installed as part of your system.
With the conceptual design established, calculations are required to predict how size, materials, and configuration will affect the desired shielding factor. Formulas to perform these calculations are available here. For more complex configurations, we can perform a number of proprietary algorithms to approximate the performance of your system. These algorithms cover a variety of shapes, sizes, layers, materials, operating intensities, and frequencies. After calculations, we can offer a guaranteed shielding performance, which we can validate in our in-house testing facility.
Amuneal has a core competency in the modeling of magnetic shielding strategies. Through our proprietary software, we are able to provide you with guaranteed shielding solutions as well as finite element analysis of your specific applications. When in need of the most demanding performance, our technical staff is a regular partner to the country's leading research laboratories and high tech industries. With over 45 years of experience in the design of magnetic shields and a unique understanding of magnetic materials, we will work with you closely to create an accurate model that meets your shielding needs.
Following the placement of your order, our engineering staff will transform your design concept into a production-ready 3D digital model and detailed shop drawings. Encompassing material optimization, joints consideration, mounting fasteners, and final tolerances, our 3D modeling process is unprecedented in our industry and allows for the fabrication of shields that meet your magnetic and dimensional requirements. We encourage you to be highly involved in this part of the process to ensure that the finished shield will seamlessly integrate into your system.
With a core competency in precision metal fabrication developed over the last 45 years we have the confidence and track record to take on the most challenging projects.
Our three Philadelphia-based facilities offer over 60,000 square feet of flexible manufacturing space. Filled with skilled machine operators, fabricators, and craftsmen alike, we balance state-of-the-art fabrication equipment and best manufacturing practices with a focus on the impact of shielding performance. Our continued investment in our staff, our equipment, and our facilities allows us to increase the depths of our product offerings and enables a systemic approach to even the most demanding applications.
We control all manufacturing operations through a networked business system that allows for real-time tracking of hundreds of in-process jobs at any given time. Our commitment to lean manufacturing principles, cutting-edge technologies, and "virtual" tooling for quick set-ups positions us as one of the most responsive partners in the industry. Our flexibility to handle prototype quantities and high-volume production runs alike is due to our unique blend of operations experts and experienced operators all working to redefine the concept of custom fabrication.
The highest performing shields, like those fabricated from Amumetal and Amunickel, require a special process called Hydrogen Annealing to achieve optimum performance. Amuneal remains the only provider of magnetic shielding with this in-house capability and thus the deepest knowledge, expertise, and ability to exert complete control over this critical step.
Hydrogen Annealing should always be the final step in the manufacturing process, as any shock or vibration to the shield after annealing will degrade the material's performance. Strict adherence to the specified annealing cycle guarantees optimum magnetic shielding characteristics by increasing the material's permeability and shielding effectiveness by 40 times on average. After the annealing cycle, materials must be handled with care as they are extremely sensitive to shock, vibration, and stress.
At Amuneal, providing solutions means providing quality. Our operations ensure that our customers receive products that meet or exceed the dimensional and magnetic requirements of their specific application.
Our fully documented Quality Control system conforms to MIL-1-45208A, and calibration of our test and measuring equipment conforms to MIL-STD-45662A. We inspect completed shields for mechanical compliance and electrically test every furnace load of Hydrogen Annealed shields in accordance with ASTM A698-74. We then collect and analyze this data statistically (SPC) to predict and correct trends and to ensure consistent performance.
We perform specialized magnetic testing to simulate your environmental requirements by isolating frequencies from DC to 100KHz. Strict adherence to these processes assures that each shield meets the specified requirements of each application.
At Amuneal, we strive to provide full service solutions to our customers. From the initial contact to the successful completion of testing and customer sign-off, we are committed to your complete satisfaction.
We're driven by details and the goal of making your entire experience as seamless and straightforward as possible. From our very first discussion, we work to define your true needs.
We know that price, quality and dependable deliveries are important to each project; however, it is our focus on your subjective needs that helps us to define what we call the extra 10%. We see the extra 10% as an opportunity to work with your internal team to ensure that you receive the highest quality components possible with each detail considered and executed properly. We go above and beyond what you have come to expect from traditional fabricators, taking the time to learn about your products, your applications, and your priorities to show you new materials and new strategies to continually improve the performance of your projects.
We are committed to the success of each project and are wholly focused on ensuring that we exceed your expectations in all areas. The extra 10% is defined by our collaborative spirit, passionate generosity, expertise, integrity, and flexibility that come from a true love of making things. We believe that it is the extra 10% that truly defines Amuneal as your partner on a project, rather than just another vendor. Give us a call. Let us know what we can do for you.
Our 50-year focus on magnetic shielding theory and design has made us a chosen partner for technology-based businesses looking to enhance the performance of their products. Our team of in-house magnetics experts combines with a cutting edge approach to engineering and fabrication to offer fully developed magnetic shielding strategies from initial concepts through high-volume production.
